4130 Carbon Steel Pipe

Confirm grade 4130, OD, wall thickness, length, ends, heat treatment condition, quantity, destination port, packing method, NDT needs, and whether EN 10204 3.1 MTC or third-party inspection is required.

4130 is a Cr-Mo alloy grade chosen for higher strength and specific mechanical applications, not general mild structural service. Mild carbon ERW/seamless grades are more common for general construction and low-pressure lines. Share design requirements for a practical recommendation.

We can coordinate mill test certificates (typically EN 10204 3.1), packing lists, commercial invoice support, heat identification, loading photos, and optional SGS, BV, or Intertek inspection before shipment.

Send the required grade or standard, dimensions, quantity, destination port and application. Add surface, processing, packing or inspection requirements when they affect the order.

Use the project specification and end use as the starting point. Share any required reference such as 4130, ASTM A519, SAE 4130 practice as contracted, AISI 4130, together with forming, welding, corrosion or service conditions, so the quotation follows the intended application.

The material specification, dimensions, quantity, processing, surface, packing and destination all affect the quotation. Final commercial terms are provided against the submitted RFQ.
